Hello nefmoto!
I am currently looking for a problem causing potential fueling issues that are bothering me, especially the Lambda Controller values at Group 1.
Please find attached the logfile. I was trying not to ecceed the 3k rpm.

Setup:
1.8t AUQ
630cc Bosch injectors
3bar FPR
3" MAF
Sytec 300l/h fuel pump
K04-064 - TTE420

I have checked all the intake for leaks, vacuum seems to be ok, replaced fuel filter.
In addition there is a (+- 20-25) positive Lambda Controller correction in Group 001 at idle after clearing the LTFT/STFT.
What would you recommend to check?
Any help appreciated  

KRKTE - 0.05195 wondering if I should increase it to ca. 0.05295 due to E5 pump gas.

TEMIN - 0.70 ms

TVUB:

7.96		2.07
10.00		0.96
11.97		0.69
14.01		0.46
15.98		0.40

It worked ok before with 430cc injectors and stock fuel pump.
I will measure the fuel pressure.
Is it necessary to switch to 4bar FPR with Sytec pump?

This interests me, pump flow / frp size. I have 265l/h frp stock 4 bar full 'e85'. for better diffusion/spraying or other is there any interest in switching to frp 4.5/5 bar?

thank you, yes that seems logical. I have never checked my fuel pressure on my 1.8t, the sl racing 265l/h and frp 4 pump are recent but nothing proves to me that I have 4 bar. I imagine I need a special gauge to connect to the rail pipe where I don't remember if there is a sensor... I was looking for why I had oscillations in idle in fact I turned much too rich e85 winter must be around 60 /65% obliged to remove all my cold start maps I reduce I just have fkstt left at 8% and that will end up in stock. and 0280158117 krkte 0.0704 . by the way if someone can give me the complete list of variables to log the fuel because I must have forgotten some. thank you
